Tallinna Tööstushariduskeskus Saturn Referaat Tallinn 2014 Sissejuhatus Saturn is one of the most interesting planets in the solar system. It is the sixth planet in the solar system, and is most famous for its stunning array of rings. It is a very easy planet to pick out in the sky because it is one of the brightest lights in the shy. It also has a very faint greenish color that makes it stand out from the rest of the objects in the sky ("Astronomy for Kids"). Saturn is the second largest planet in the solar system, Jupiter being the only planet that is bigger. It also has at least eighteen moons, more than any other planet in the solar system

lethal radiation. Yet the legacy of supernovas is as close as our own bodies. The carbon in our cells, the oxygen in the air, the silicon in rocks and computer chips, the iron in our blood and our machines--just about every atom heavier than hydrogen and helium--was forged inside ancient stars and strewn across the universe when they exploded billions of years ago. Eager to understand our origins and, in some cases, simply wild about things that go bang, astronomers have been struggling for decades to understand why stars that shine peacefully for millions of years suddenly blow up. Lately they've had two big breaks. One is a revelation about potent blasts of high-energy gamma rays that come from distant points in the heavens. For decades astronomers have puzzled over their origins, but space probes recently clinched the answer, which Woosley proposed more than
1 Wave energy Introduction to wave energy There are several possibilities to harvest different forms of energy from the sea. One of these options is the usage of waves for the generation of electricity. The devices needed to perform this task are called wave energy converters. Wave energy is indirect solar energy in twice. At first there is the wind, which is caused by variations in atmospheric pressure due to a differential solar heating of earth's surface by the sun. Different regions of pressure drives a force which rises a movement of atmospheric air masses that causes the earths wind system. If wind strikes over the surface of an open water, waves are induced. First they are very flat with only a low level of energy. When there is a long distance over

a. I really need some money. I should get a job. b. I really need some money. Therefore, I should get a job. Non-arguments Not all passages are arguments. Examples: Simple non-inferential passages where nothing is said to be proved. ● Be careful! (Warning or piece of advice) ● I believe that good behaviour is always rewarded (Statement of believe or opinion) ● The protest started at 3pm. The main place was crowded… (Report about something) Expository passages where we develop an opening sentence (without attempting to prove it). ● There are two types of elephants: the African elephant and the Asian elephant. African elephant has large ears and both females and males have tusks. The Asian elephant has smaller ears and only males develop tusks. Conditional statements of the form “if...then…”. ● If it rains, then I will take my umbrella. Conditional itself is not an argument
